This piece of nouvelle génération is rigorously identical to the original factory assembly on the engines Rotax Evo. Elle garantit une étanchéité parfaite entre le mécanisme de la valve et le cylindre, preventing exhaust gas leaks that could impair the operation of the valve control system and the engine’s overall performance.

ℹ️ Note technique: This seal has specific dimensions of 6 mm (inside diameter) x 11 mm (outside diameter) x 3 / 4.5 mm (thickness). It is crucial for the proper operation of the engine’s pneumatic or electronic valve system Rotax Evo.

Description and Features

• Genuine Manufacturer Part: Fabriqué par BRP-Rotax, this element certifies the quality, dimensional tolerance and perfect compatibility with your engine Rotax Max Evo.

• Étanchéité Vitale: The oil seal prevents pressurized exhaust gases from traveling up along the guillotine stem. A leak at this point would disrupt valve control (loss of efficiency of the pneumatic actuator or solenoid on electronic versions) and result in a loss of power, particularly at medium engine speeds.

• New Generation Version: Designed to withstand the high temperatures and chemical stresses of the exhaust environment of competition 2-stroke engines.

• Sustainability: Although robust, this seal is a wear part subject to significant thermal and mechanical stresses. Its regular replacement is recommended when servicing the valve system.

📖 Michel’s Tip

"Michel, our engine expert, recommends: Replacing this oil seal is a simple but delicate operation. When removing the old part, take care not to scratch the housing in the cylinder or the guillotine shaft. When refitting, make sure the seal is perfectly flat and fully seated (using a socket of the appropriate diameter, for example), and above all that it is oriented correctly (the sealing lip must face inward, toward the side exposed to gas pressure). Take this opportunity to check the condition of the guillotine shaft: if it is marked or worn, the new seal will not be effective.

⚠️ Conseil de sécurité: The valve system is essential to the driving character of your Rotax Evo. Incorrect installation or a worn seal can cause the valve mechanism to break. Handle the parts with care and ensure that the housing is clean before installation.
